PAPER-CUTTER.

Specification of Letters Patent.

Patented June r7, ieio.

Application filed November 26, 1918. Serial No. 264,269.

To all whom it may concern:

Be it known that we, ALBERT Bowman and Rosoon A. HArrono, citizens ofthe United States, residing at Groveton, in the county of Coos and Stateof New Hampshire, have invented certain new and useful Improvements inPaper-Cutters, of which the following is a specification.

This invention relates to cutting implements, and more especially tothose which travel over the material cut; and the object of the same isto produce a cutter especially intended to cut paper when in roll form.It is well known that in paper mills there are many large rolls of paperthat are too poor for the market, and therefore, they have to go throughthe paper engine again. In order to put this paper through the feeders,it must be cut off the roll and put through again two or three sheets ata time. It is quite diflicult to cut paper off a roll where it istightly wound thereon, and the ordinary method is to run a sharp knifeor tool under several sheets, cutting them from the roll by hand. Thisis a laborious process, and the primary object of the present inventionis to produce a tool by which it can be done andmuch time saved.

For details we refer to the following specification and claim and to thedrawings herewith, and in which Figure 1 is a side elevation of thistool partly in section.

Fig. 2 is a bottom plan view.

Fig. 3 is a detailed perspective of the cutter.

The tool is much like an ordinary hand plane. It comprises a body orbase 1 having a V-shaped channel 2 along its cutting face, a handle 3 atits rear end, and an upstanding knob 4 forming a handle at its frontend. The forward portion of the body or base is low and substantiallyflat, whereas the rear portion is raised and contains a chamber 5 whichin the present instance is shown as substantially rectangular. Thiscontains the shank 6 of the cutter, best seen in Fig. 3, which shank hasan upright slot 7 in its body and a notch 8 in its rear edge. The lowerend of the plow carries a V-shaped plow 9 adapted to fit in the channel2 when the shank of the cutter is raised suflioiently high, and at thefront end of the plow is the .knife 10. The entire cutter may be ofmetal,

but the knife is highly tempered and substantially triangular as seen,its edge along the top rising from its tip and being capable of cuttingseveral sheets of tough paper without becoming rapidly dulled.

l Vhile any suitable means may be employed for adjusting the position ofthe cutter, we prefer to pass a set screw 11 through the rear portion ofthe body 1 of the implement, and provide one end with a knob or nut 12,and after the shank has been placed in the chamber 5, the knob or nutcan be tightened to hold it so. For finer adjustments an L-shaped lever13 is pivoted at 1 1 within the body of the device, and its front end 15enters the notch 8 while its other end is pierced for the reception of ascrew 17 pivoted at 18 in a lug 19 upstanding from the body as shown inFig. 1. A spring 20 is preferably interposed between the upper end 16 ofthe lever and the lug 19 so as to normally press the upper end of thelever to the rear. A nut 22 is threaded onto the screw behind the end 16and it may be turned up to compress the spring and alter the position ofthe lever. By this arrangement it is quite obvious that the exactvertical adjustment of the cutter may be obtained, and the cutting pointand edge of the plow may be very nicely set, provided only that the nuton the set screw 11 is loosened a trifle before adjustment is attempted,after which it can be set up so as to hold the parts in adjustedposition.

In the use of this device, the roll of paper is brought to the workman,or the workman goes to the roll with the tool, and passes it rapidlyacross the face of the roll on a line parallel with the axis thereof,reciprocating the tool after the manner of an ordinary hand plane. Thecutter should be set so that the tip of the knife may run'undcr three orfour thicknesses of paper, and after each movement of the device acrossthe roll, the sheets of paper out thereby are withdrawn and passed alonginto a receptacle, from which they are carried to the engine for renewedtreatment. We find by experience that a tool of this kind may be used along time without resharpening, and the work is greatly expedited.

Having thus fully described our invention,
